Walkthrough

The changes in this pull request primarily focus on the OBJLoader class within examples/obj-loader.ts. The load method has been updated to use a new request function instead of this.request, streamlining the resource retrieval process while maintaining the existing logic for parsing OBJ files. Import statements have been reorganized, and minor formatting adjustments have been made to improve code readability.

Changes

File	Change Summary
examples/obj-loader.ts	Updated load method to use request function; reorganized imports; minor formatting changes.

Possibly related PRs

• Add mesh loader #2426: The load method in the MeshLoader class has a similar signature and functionality to the load method in the OBJLoader class, both returning an AssetPromise<ModelMesh> and handling resource loading.

🐰 "In the code where the OBJ files play,
A new request leads the way.
With imports neat and formatting bright,
The loader hops with pure delight!
Parsing meshes, oh what a sight,
In the realm of code, all feels right!" 🐇

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
